XXXVI.—Descriptions of Seventeen new Genera of Ichneu- 
monide from India and One from Australia. By P. 
CAMERON. 
In this paper I have described a number of well-marked 
genera of Ichneumonide, mostly belonging to the Joppini 
and the Heresiarachini. Very little has been published upon 
the Joppini occurring in India, but in all probability they will 
prove to be quite as numerous there as in the Neotropical 
Zoological Region, which has hitherto been looked upon as the 
headquarters of the group. ‘T'wo genera of Indian Joppini 
have been described by Dr. Kriechbaumer in Ent. Nachtr. xxiv. 
1898, where he also revises the genera; and there is a further 
revision of them by Mr. W. H. Ashmead in Bull. U.S. Nat. 
Mus. xxiii. 1900. The Heresiarachini are easily known by 
their toothless mandibles. This tribe appears to be well 
represented in India, but no species has hitherto been recorded 
therefrom. ‘The species are in the collection of Mr. G. A, J. 
Rothney.
